What is Neurofeedback?
Neurofeedback is direct training of brain function, by which the brain
learns to function more efficiently.
We observe the brain in action from moment to moment. We show that information
back to the person and we reward the brain for changing its own activity
to more appropriate patterns. This is a gradual learning process.
It applies to any aspect of brain function that we can measure. Neurofeedback
is also called EEG biofeedback, because it is based on electrical brain
activity, the electroencephalogram, or EEG.
Neurofeedback is training in self-regulation. It is simply biofeed-
back applied to the brain directly. Self-regulation is a necessary part
of good brain function. Self-regulation training allows the system (the
central nervous system) to function better.
How is Neurofeedback Done?
We apply electrodes to the scalp to listen in on brainwave activity.
We process the signal by computer, and we extract information about certain
key brainwave frequencies. (All brainwave frequencies are equal, but some
or more equal than others….) We show the ebb and flow of this activity
back to the person, who attempts to change the activity level. Some frequencies
we wish to promote. Others we wish to diminish. We present this information
to the person in the form of a video game. The person is effectively playing
the video game with his or her brain. Eventually the brainwave activity
is "shaped" toward more desirable, more regulated performance. The frequencies
we target, and the specific locations on the scalp where we listen in on
the brain, are specific to the conditions we are trying to address, and
specific to the individual.
How do you know how to train a particular part of the brain?
Over the years, certain training protocols have been developed that
are helpful with certain classes of problems such as attention, anxiety
and depression, seizures and migraines, as well as cognitive function.
There are a number of assessment tools we use to help us decide which protocols
to use. These are simple neurodiagnostic and neuro-psychological tests. |
